So.... not much?
What kills me is that it's lost on the public that the US destabilized the region which allowed groups like this to emerge. And it's US intervention that radicalizes these groups in the first place. Al-Qaida in Iraq didn't exist before the US invasion of Iraq. It was formed to fight the US troops there. ISIS is an offshoot of Al-Qaida in Iraq. And what's more, they have all the weapons we gave to the Iraqis who abandoned them while fleeing ISIS. So now we're bombing the armored humvees we built and sent there in the first place.
Gee, maybe don't interfere in the first place? The only people who are winning are the weapons makers in America.
World Peace's biggest problem: War is profitable.
